ELECTRIC HEATER.

Application filed March 30, 1923.

To all whom it may concern: 1

Be it known that I, JosEPH GAssER, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented new and useful Improvements in Electric Heaters, of which the following is a specification.

This invention relates to electric heaters and particularly to, heating systems which may be applied to entire houses, and the principal object of the invention is to provide a device utilizingone or a plurality of electric heating elements in a heating chamher, the walls of which are entirely curvilinear reflecting surfaces.

Another object is to construct a heater of the above nature and including means for passing a current of air through the heating chamber in such manner as to transfer substantially all of the heat generated in said chamber to the air passed therethrough.

Another object is to provide a heater of this nature with reflecting baflles which pass the heat back and forth through an air conducting medium thereby preventing loss of heat by transmission to the surrounding atmosphere.

With these and other objects in view as will be more apparent, the invention consists in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which The'single figure isa vertical sectional view of an electrical heater constructed according to my invention.

Referring to the drawing in detail, 10 represents the base "of the heater which may be of any suitable and shape to support the other parts of the heater as hereinafter set forth. Supported upon the base 10 is the main body or outer shell 11 of the heater which may be of any size or shape but is preferably of cylindrical shape with convex ends as shown. This outer shell 11 is provided at 12 with an air inlet pipe and at the top with a plurality of service pipes 13 leading to the various rooms or locations where the air is to be utilized as is customary in hot air furnaces.

Secured to the inside of the shell 11 by webs 1 1 or the like, bolted to the shell 11 Serial No. 628,863.

are the upper and lower curved walls 15 and 16, respectively, of the heating chamber. These walls are connected by an interposed cylindrical member 17 which wit-h the ends 15 and 16 form the complete heating chamber. A coil or conductor pipe. 18 is arranged centrally of the heating chamber with one end piercing the wall and connectingwith inlet pipe 12 and the other end emptying into the space between the heating chamber and the shell 11.

Preferably the walls of the heating cham- I her are of copper-alloy and are highly polished interiorly so as to furnish as nearly as possible, perfect reflecting surfaces. The exterior of the heating chamber may be coated with lampblack, and it is preferred to so coat the exterior of the coil 18 so as to effect more readily the absorption of the heat.

A humidifier is indicated at 19 and is fed from a tank 20 which is filled from a water supply pipe 21 under the control of a float valve device 22.

Mounted in the pipe 12 is a forcing fan 23 which is driven by a. motor 24 which may be turned on and ofi at switch 25.

vThe heating elements for the heating chamber comprise coils 26 and 27, of any suitable and desirable design mounted on insulators 28 and 29 respectively, inserted in the bottom and top, respectively, of the shell 11 and preferably threadedly engaging reflectors 16 and 15, respectively. The coils 26 and 27 are controlled respectively from switches 30 and 31 mounted adjacent each other. Each of the coils 26 and 27 carries at its inner end a small hood-like reflector 32 for insuring the throwing of the heat from each coil against the adjacent reflector 16 or 15 as the case may be.

The curve of each of the reflectors 15 and 16' is such that substantially all of the heat from the contiguous heating element is caught and'cast in a straight line across to the opposite reflector or against the coil 18. That heat which is. re-refiected is then focused on the coil or conductor pipe 18,

ing elements is absor ed by theconducting pipe and transmitted to the air passing therethrough. T

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the parts may be varied Without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein shown nor to anything less than the whole of my invention limited only by the appended claims.

What I claim is 1. In a deviceof the class described, the combination of an outer shell, a plurality of reflectors supported therein and forming a heating chamber suspended in said outer shell, a coil of tubing in said heating chamber and communicating with the space between said chamber and outer shell at one end and with the atmosphere at the other' suspended in said outer shell, a coil of tub 3. In a device of the class described, the

combination of an outer shell, a plurality of reflectors supported therein and forming a heating chamber suspended in said outer shell, a coil of tubing in said heating chamber and communicating with the space be-. tween said chamber and outer shell atone end and with the atmosphere at the other end, and heating means supported in said heating chamber.

4. In a device of the class described, the combination of an outer shell, a plurality of electrical heating elements, a plurality of reflectors each arranged in contiguity to a respective one of said electrical heating ele ments and in opposition to another of said reflectors, and forming a heating chamber suspended in said outer shell, a coil of tubing in said heating chamber and communieating with the space between said chamber and outer shell at one end and with the atmosphere at the other end.

In testimony whereof I afiix my signature.

JOSEPH GASSER.
